FTA: Why does the StopTheMadness extension want to disable input field max length? That’s a very useful feature for developers to give instant feedback to the users. I get it: a minority of people have 64+ char email addresses, but if you know the server is going to reject the POST, why not stop it before the submit?

I'm the developer of StopTheMadness, and it doesn't disable input field max length. Rather, it warns you when you paste something longer than the max length; otherwise, without the warning, your paste gets silently truncated, and you wouldn't know it.

I love/hate this page on your website demonstrating all the user-hostile things web developers can do: https://underpassapp.com/StopTheMadness/test.html

It definitely makes a great sales pitch.

ok perfect, thank you!

Fun fact, I bank with a bank I won’t name, who has a change password flow that allows for up to 32 character passwords.

Their login page only allows for 16 character passwords using the max length. This would truncate my password on login.

Backend handles the longer password just fine though.

We might bank with the same bank!

To paste a value that’s too long, then remove some part in the middle. Otherwise, it’s truncated.
